Woven articles from synthetic self twisted yarns
View Patent ↗A woven panel is formed from at least one first polymer yarn and at least one second polymer yarn wherein the second polymer yarn has a core. The core yarns provide mechanical strength for the woven material in supporting the coreless yarns when used in load bearing articles such as the seat or back portions of an article of furniture.
1. A method of making a woven panel adapted for use in an article of furniture, said method comprising:
providing a plurality of first synthetic polymer yarns having substantially elliptical cross sections,
providing a plurality of second synthetic polymer yarns,
self-twisting said plurality of first synthetic polymer yarns into a twisted shape,
heating said plurality of first synthetic polymer yarns to a temperature sufficient to cause said first synthetic polymer yarns to retain their twisted shape, wherein said heating of said first synthetic polymer yarns occurs after said self-twisting of said first synthetic polymer yarns, and
weaving said first and second synthetic polymer yarns together to form a woven panel of adjacent yarns therefrom while said first synthetic yarns have a self-twisted shape, wherein said heating is insufficient to cause adjacent yarns to adhere to each other.
2. The method of claim 1 , further including self-twisting said plurality of second synthetic polymer yarns into a twisted shape, and heating said plurality of second synthetic polymer yarns to a temperature sufficient to cause said second synthetic polymer yarns to retain their twisted shape.
3. The method of claim 2 , wherein said heating of said second synthetic polymer yarns occurs prior to said self-twisting of said second synthetic polymer yarns.
4. The method of claim 2 , wherein said heating of said second synthetic polymer yarns occurs after said self-twisting of said second synthetic polymer yarns.
5. The method of claim 2 , wherein said second synthetic polymer yarns are twisted into self-twisted yarns selected from the group consisting of S-twist yarns and Z-twist yarns.
6. The method of claim 1 , wherein said first synthetic polymer yarns are twisted into self-twisted yarns selected from the group consisting of S-twist yarns and Z-twist yarns.
7. The method of claim 1 , forming at least one groove and at least one visual representation of a stripe in the outer surface of said first synthetic polymer yarns extending substantially in a longitudinal direction along the length of said first synthetic polymer yarns.
8. The method of claim 7 , wherein said first synthetic polymer yarns have a deformed outer surface and a non-uniform cross section along their length.
9. The method of claim 1 , forming at least one groove and at least one visual representation of a stripe in the outer surface of said second synthetic polymer yarns extending substantially in a longitudinal direction along the length of said second synthetic polymer yarns.
10. A method of making an article of furniture having a woven panel, said method comprising:
providing a frame in the shape of an article of furniture,
providing a plurality of first synthetic polymer yarns having substantially elliptical cross sections,
providing a plurality of second synthetic polymer yarns,
self-twisting said plurality of first synthetic polymer yarns into a twisted shape,
heating said plurality of first synthetic polymer yarns to a temperature sufficient to cause said first synthetic polymer yarns to retain their twisted shape, wherein said heating of said first synthetic polymer yarns occurs after said self-twisting of said first synthetic polymer yarns,
weaving said first and second synthetic polymer yarns together to form a woven panel of adjacent yarns therefrom while said first synthetic polymer yarns have a self-twisted shape, wherein said heating is insufficient to cause adjacent yarns to adhere to each other, and
attaching said first and second synthetic polymer yarns to said frame.
11. The method of claim 10 , further including self-twisting said plurality of second synthetic polymer yarns into a twisted shape, and heating said plurality of second synthetic polymer yarns to a temperature sufficient to cause said second synthetic polymer yarns to retain their twisted shape.
12. The method of claim 11 , wherein said heating of said second synthetic polymer yarns occurs prior to said self-twisting of said second synthetic polymer yarns.
13. The method of claim 11 , wherein said heating of said second synthetic polymer yarns occurs after said self-twisting of said second synthetic polymer yarns.
14. The method of claim 11 , wherein said second synthetic polymer yarns are twisted into self-twisted yarns selected from the group consisting of S-twist yarns and Z-twist yarns.
15. The method of claim 10 , wherein said first synthetic polymer yarns are twisted into self-twisted yarns selected from the group consisting of S-twist yarns and Z-twist yarns.
16. The method of claim 10 , forming at least one groove and at least one visual representation of a stripe in the outer surface of said first synthetic polymer yarns extending substantially in a longitudinal direction along the length of said first polymer yarns.
17. The method of claim 16 , wherein said first synthetic polymer yarns have a deformed outer surface and a non-uniform cross section along their length.
18. The method of claim 10 , forming at least one groove and at least one visual representation of a stripe in the outer surface of said second synthetic polymer yarns extending substantially in a longitudinal direction along the length of said second synthetic polymer yarns.
19. The method of claim 10 , wherein said first synthetic polymer yarns are attached to said frame during said weaving step.
20. The method of claim 10 , wherein said first and second synthetic polymer yarns are attached to said frame when in the form of said woven panel.
